Japanese-founded battery manufacturer AESC has announced a strategic supply partnership with US BESS system integrator Prevalon Energy.
Announced 13 June, under the agreement, AESC will supply battery energy storage system (BESS) cells and modules used within the Prevalon Energy Storage Platform, supporting over 10GWh of utility-scale BESS deployments over the next three years.
According to the companies, it will support deployments across the Prevalon Energy Storage Platform, including HD5 DC, the recently launched HD5 AC, and Hybrid Power Stabiliser (HPS) solutions, renewable integration, data centre power infrastructure, and other “critical energy applications.”
AESC and Prevalon have both recently undergone changes in company structure.

In May, AESC sold majority stakes in its battery manufacturing assets to US startup Fixx Energy. In a deal signed prior to the sale, the
Fixx Energy was founded by venture capitalist Brett Conrad and is headed by CEO Jeff Juger, who was formerly with Chinese solar PV manufacturer JinkoSolar, which similarly sold majority stakes in its solar manufacturing assets to private equity firm FH Capital, also in May.
While AESC is headquartered in Japan, its majority owner is China’s Envision Energy, which bought the battery manufacturer from its founder, carmaker Nissan, in 2018. To comply with the ‘One Big Beautiful Bill Act’s’ (OBBBA’s) rules on material assistance from prohibited foreign entities (PFEs) and foreign entities of concern (FEOCs), Envision sold the lithium iron phosphate (LFP) cell factory in Smyrna, Tennessee, to Fixx Energy in March. Envision remains involved in the Tennessee factory via a technology licensing agreement.
AESC was also one of the first US-based electric vehicle (EV) battery cell suppliers that repurposed its production lines to make cells for stationary BESS applications and is a supplier to energy storage system integrator and technology provider Fluence for its US projects.
Edward Hou, senior vice president at Envision Energy said of the AESC and Prevalon deal, “The scale of this agreement underscores the surging global demand for reliable, high-performance energy storage. Together with Prevalon, we are committed to supporting the next generation of power infrastructure with safe, intelligent, and sustainable energy storage solutions.”
Prevalon Energy, a spin-out from Mitsubishi Power Americas, specifically the Mitsubishi Heavy Industries’ BESS division, became an acquisition target for solar PV solutions provider Nextpower, formerly Nextracker, in late May, in a deal worth US$365 million, expected to close in Q3 2026.
Nextpower also recently acquired Spain-based Zigor Corporation and its US subsidiary, Apex Power. The transaction was valued at approximately US$80.5 million and came shortly after Nextpower began testing its own power conversion technology earlier this year.
